Features
•AW8155 is a second-generation music amplifier with anti-breaking sound, super TDD suppression and ultra-low EMI. Ultra-low distortion and unique anti-breaking sound technology eliminate the breaking sound produced during playback, bringing you wonderful music enjoyment.
•AW8155 adopts Awin’s proprietary RNS technology and clean sound technology to effectively suppress the generation of TDD noise.
•AW8155 has two power levels of 0.65W and 0.85W, suitable for different speaker specifications, strictly controlling power output and effectively protecting the speakers.
•AW8155 has built-in excellent Pop-Click noise suppression circuit, which effectively avoids Pop-Click noise when the chip is turned on and off.
•AW8155 has built-in over-current protection, over-temperature protection and under-voltage protection functions, which effectively protect the chip from being damaged under abnormal working conditions.
•The AW8155 is available in a tiny 1.5mm x 1.5mm FC9 package and is rated for operation over the -40°C to 85°C temperature range.
